In episode four, Emma and Dexter take a holiday together in Greece, where the boundaries of their friendship are tested by sun, sea, sand and a single bed. For this, the production was filmed on the island of Paros, one of the Cyclades group. We see the harbour at Naousa, on the north of the island, as well as several of the island’s beaches and the whitewashed backstreets of the main town, Parikia, on the northwest.
